the macro i'm using is :

// This macro creates a selection that is the difference
// between two selections in the ROI Manager.
requires("1.36b");
orig = getImageID();
setBatchMode(true);
if (roiManager("Count")!=2)
exit("Two ROIs in ROI Manager required");
roiManager("Select", 1);
run("Create Mask");
rename("Mask1");
mask1 = getImageID();
roiManager("Select", 0);
run("Create Mask");
mask2 = getImageID();
imageCalculator("SUB", mask2, mask1);
run("Create Selection");
roiManager("Add");
selectImage(orig);
roiManager("Select", 2);
roiManager("Rename", "Soustrait");
